Vintage Seymour Duncan Convertible 60 watt 2 Channel Guitar Tube Amplifier. For sale is a very rare seymour duncan guitar amp head. It was tested and works great.

I built this amp 6 years ago, but it’s too loud for me to open it up when I play in my house. I assembled it from a kit by Boothill Amps, so the parts are high quality. You can look at his website for more information. It’s a 5-watt 5F1 “Fender Champ” circuit. The speaker is an 8-inch, 4-ohm ceramic Warehouse G8C. I bought a tube set directly from Dave at Boothill Amps because he said that a USA-made tube rectifier would be more reliable and keep the amp at the proper voltages. The newer modern production 5Y3 tubes run at higher (hotter) voltages. Keep this in mind if you plan on replacing the 5Y3 rectifier (far left tube, V3) and/or the 6V6 power tube (middle tube, V2). He sent me a USA-made RCA 5Y3 (rectifier) tube and a USA-made RCA 6V6 power tube. These are vintage tubes, but I’ve read that rectifier tubes last a long time. The V1 preamp tube (far right) is a brand new modern Russian-made TOL-SUNG AX7. I will include these three tubes with the sale. The transformers I used are now difficult to find: a USA-made ClassicTone 40-18019 (Power Transformer) and a ClassicTone 40-18115 (Output Transformer). The pine cabinet is unbranded and came with the kit. It’s well-made and covered with raw (unlacquered) tweed. See photos and video for details.

Beautiful 1961 Bogen Challenger CHA-10 Vintage amplifier. Completely restored plug and play ready! Glorious single ended 6L6 sound! Think way louder Fender Princeton. Amp is mostly stock with a few useful mods. The tone switch has been changed to way more useful tweed Fender tone pot circuit. The phono pot is now a master volume. 1/4 input and speaker out jacks. 4, 8 and 16 ohm outputs. I added a 3 prong power cord and fuse for safety. Still has the original hang tag from the power cord! All original high testing Bogen tubes-6AV6 (Blackburn Mullard), 6AU6 (RCA), 6L6GC (GE) and EZ81 (Blackburn Mullard). I haven’t done one of these for awhile, so video is of one I did while ago the same way so you can hear how it sounds.
The unit has been partially recapped and new grounded power cable. There is wear from use/storage like scratches, scuffs and dust. 1 x 12AX7 Sylvania. 1 x 35C5 GE. 1 x 35C5 IEC. 1 x 35W4 unbranded. Please contact me if you have any questions.

Up for sale, a 1963 Gibson GA-30RVT Invader in great condition, complete with the original footswitch. Please examine the pictures closely for a complete description. This GA-30RVT has a complete vintage tube set and a pair of original Jensen speakers-a 12″ C12R ceramic magnet driver and a 10″ P10R alnico magnet speaker. This amp is surprisingly quiet and sounds great. Cleans are clear and bold. The Reverb is unique and acts as a volume control as opposed to a wet/dry mix. This allows the effect to be heard with the amp volume otherwise at zero (a particularly ethereal sound), and also causes the reverb to have its own natural overdrive characteristics when you crank it. The Tremolo is particularly dimensional and deep with a strong throbbing quality. The circuit is original and professionally serviced only as strictly necessary, with new electrolytic caps and a modern three-prong power cable. All of the original transformers are intact and all of the pots are original as well. This model has 8 Tubes and include a matched pair of Westinghouse 7591 power tubes, a Amperex Bugle Boy rectifier, and original RCA-branded valves in the preamp. The amp schematic appears to be identical to the early and coveted Epiphone EA-12 RVT Futura. The speakers are both original to the amp. In addition, there is a switchable external jack that cuts off the connection to the output transformer, allowing you to easily use this as a stand alone speaker cabinet. The cabinet construction is impressive and the overall unit is unbelievably clean. The amp features its original smooth brown covering and two-tone grillcloth, with a large Gibson badge on the face, almost pristine graphics on the aluminum faceplate, and a full complement of reflector cap knobs. The original (hard-wired) two-button footswitch is included.
